The correlation that represents the strongest relationship is:

a. +.68

Explanation:

• Correlation values range from -1 to +1.
• The closer the value is to -1 or +1, the stronger the relationship.
• Positive correlations (e.g., +.68) indicate a direct relationship, while negative correlations (e.g., -.43) indicate an inverse relationship.
• A correlation of +.68 is stronger than the others listed.

Here are 5 questions to expand on this:

1. What does a correlation value of +1 indicate?
2. How does a negative correlation differ from a positive one?
3. In what fields are correlations typically used to interpret relationships between variables?
4. What does a correlation of 0 mean?
5. How can you determine if a correlation is statistically significant?

Tip: Always remember that correlation does not imply causation.
